has anyone tested if it is 5v and not a mislabeled 12v?

Hello Dear ,this adapter is DC5V ,not 12V .Best regards

How many W2812B strips can I connect together with this?

All depends on how many LEDs/what brightness/which color for each LED. At 5V, each LED draws about 50mA, when set to its full brightness.

is this the correct power supply for btf-lighting ws2813 16.4ft 60leds/m individually addressable rgb led flexible strip light 16.4ft 300leds?

DC5V6A 30W is OK for WS2813 16.4FT 300LED LED Strip . But we recommend you light up some chasing color lighting effects .Light up 1 color（red or green or blue) 0.1W/LED . Light up 2 colors (red+green) 0.2W/LED , Light up 3 colors (red+green+blue=mixed white) 0.3W/LED .Please don't light up mixed white . Any other question , please contact us support@btf-lighting.com Best regards BTF-LIGHTING

Does the 5v10a power supply maintain 5V constant even at 80% (8A) output or does it drop below 4.7V?

I don't know for sure. However, if your standard split system 200 Amp service fails, you have a lot bigger problems than fluctuating voltage converted by this power brick. The only way your question could be answered would be to test it in person. But you could only do that if you purposely dropped the source voltage by 20%. You could do that, but I think it would be a waste of time. You would need some type of voltage regulation equipment, and the test would take a lot of time to set up. The bottom line is, most American (utility provided) residential power systems provide consistent voltage/current outputs to homes that are not going to fluctuate 20% (so that you are left with 80% output).
